CLARENCE DARCY LEVEY, OF NEW YORK, N. Y.

FIVREPROOFIN'G FOR BOOKS.

SPECIFICATION forming part of Letters Patent No. 738,744, dated September 8, 1903.

Application filed January 28 1903- Serial No. 140,851. (No model.)

To all 1077,0770 it may concern:

Be it known that I, CLARENCE DARCY LE- VEY, a citizen of the United States, residing in New York, in the State of New York, have invented certain new and useful Improvements in Fireproofing for Books, 850.; and I do hereby declare the following, in connection with the accompanying drawings, forming part hereof, to be such a full, clear, and exact description as to enable others skilled in the art to which my invention relates to make and use the same.

The object of my invention is to make a covering possessing all the qualities as regards durability, flexibility, and appearance of the coverings popularly used in binding books, document-cases,'and the like, while at the sametime possessing the valuable quality of being absolutely fireproof.

It has been found that the intense heat to which safes are subjected in burning buildings often destroys partially or entirely their I p to these should be constructed to resist them.

contents, whileany books or otherdestroy able articles not within the safeat the time are entirely consumed. A book or documentcase bound and treated in the manner hereinafterdescribed not only remains uninjured when in a safe subjected to far greater temperatures than ever attain in a burning building, but is not seriously damaged if caught in the fire entirely unprotected by any safe or covering.

It has been proposed in the past to obtain a fireproof covering for books, records, (be, and desultory and unsuccessful attempts have been made in this direction. Such attempts have, however, only resultedin cheap, untidy, and entirely unsalable products, in which the requisite quality of being fireproof is either missing from the start or deteriorates to such an extent as. to be ineffective when the test comes. It is apparent that the fireproof material forming an element of the binding should be protected from injury from such destructive agencies as continual rubbing, insects, &c., or if it is to be subjected I have devised several forms of my improved covering differing from each other in detail as tomaterial selected and relative arrangement of parts. Such changes fall with in the scope of my invention. .In the present instance the fireproof material is incasedin the ordinary leather or other coating and is supported by some stiffening material, as linen, cardboard, or the like.

For further particulars and a more detailed description reference is made to the drawings, in which Figure 1 is a view of a book embodying one form of my invention. Fig. 2 shows a slightlymodified form of the same. Fig. 3 shows a book provided with a slip-covering and illustrating another application of myinvention. Fig. 4 is a cross-section of the cover of Fig. 1. Fig. 5 is a cross-section of a portion of the cover of Fig. 2.

Referring particularly to Figs. 1 and 4, 1 represents the cover of a book. This cover may be bound in any well-known manner. 2 represents an outside surfacing of leather, linen, or any similar material. Between the sheet 3 and the covering 2 is placed a sheet of fireproof material, such as asbestos. Instead of this arrangement the modification shown in Figs. 2 and 5 may be adopted, in which 5 and 7 represent sheets of fireproof material properly stiffened and hardened to resist wear. This may be accomplished in a variety of ways. 6 represents a sheet of stilfening or other comparatively rigid material.

In Fig. 3 is illustrated a book 8, with covers 10 of any well-known form and provided The covering is ren-.

I do not wish to limit myself to the precise V structures shown in the figures of the drawings, as it is obvious slight modifications and rearrangements can be made without departing from the spirit thereof.

Having specifically described my invention,

what I claim, and desire to secure by Letters Patent, is

. l. A book-cover consisting of a sheet of comparatively rigid material having superimposed thereon fireproof material and a finishing material outside of and closely embracing the whole.

2. A book, the covers of which consist of stiffening material, asbestos superimposed thereon, and a leather finishing-surface.

In testimony whereof I affix my signature in presence of two witnesses.

. CLARENCE DARCY LEVEY.
